The Doctor: Since encountering the Weeping Angels, I've been trying to come up with a counter-measure, and I've finally figured one out.
The Doctor: I call it 'blonking'.
The Doctor: Of course, it's probably only Time Lords who can do it.
Synonymous with the word 'blink', meaning to open and close an eye. Only this kind of blink is detrimental. Performing this action could mean that one would miss when peak oil ends, when governments change, when homes become hotels, or when giants merge. In other words, you could miss a critical moment and lose a competitive advantage by performing this action.
